Microsoft announce that Advanced Communications is available from August 1, 2020.
This adds a new set of capabilities for Teams, costs $12 per user per month and may be added on to any licence that includes the Teams service.
It supports large meetings enhancing the standard Teams limits from 10,000 to 20,000 attendees, 15 to 50 concurrent events, and event durations from 4 to 16 hours. Note that these limits are already uplifted for all Teams users until 1 October, 2020 – find details of that here: https://bit.ly/3lf2fON.
It also supports integration with ISV compliance recording and contact centre solutions, and will support custom branded meeting lobbies in the near future.
